Magnetic force decreases drastically with every mm of distance. Keep in mind that every additional insulation layer (e.g., dirt, paint, rust) strongly weakens the grip. Neodymiums work most effectively in perfect adhesion; distance nullifies the force. Observe how quickly the load capacity plummet, when the product does not adhere tightly to the metal substrate. When calculating the assembly, avoid additional spacers.

The following data shows the approximate weight limit needed to start the downward movement of the magnet down along a upright steel plate (considering standard friction). This parameter is relative to the air gap between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MPL 20x3x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.70 kg / 1.54 pounds 699.0 g / 6.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.47 kg / 1.03 pounds 466.0 g / 4.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.23 kg / 0.51 pounds 233.0 g / 2.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.17 kg / 2.57 pounds 1165.0 g / 11.4 N

When placing a holder on a upright surface (e.g., a car body), it you can count on just approx. 20%-30% of its maximum pull force. Gravity and a low friction coefficient mean that holders slip easier than they detach. Planning a wall mount? Consider that the sliding force is significantly lower than the maximum static pull force. On a painted metal, the holder will slide down under a significantly smaller weight. Using a rubber layer can significantly improve the result.

2 mm	50%	1.17 kg / 2.57 pounds 1165.0 g / 11.4 N
3 mm	75%	1.75 kg / 3.85 pounds 1747.5 g / 17.1 N
5 mm	100%	2.33 kg / 5.14 pounds 2330.0 g / 22.9 N
10 mm	100%	2.33 kg / 5.14 pounds 2330.0 g / 22.9 N
11 mm	100%	2.33 kg / 5.14 pounds 2330.0 g / 22.9 N
12 mm	100%	2.33 kg / 5.14 pounds 2330.0 g / 22.9 N

A too thin steel is unable to take in the full magnetic flux, which weakens actual performance of the holder. Should you attach a powerful product to a thin surface, the magnetism will penetrate right through and the attraction force will be weaker. To achieve 100% of this neodymium's potential, you require a sufficiently solid backing of steel. The saturation effect means that on delicate walls (e.g., thin profiles), the product holds weaker. We suggest choosing the steel thickness from these parameters.

Classic neodymiums lose parameters after exceeding the maximum temperature. Protect against heat – heat can permanently damage this product. As the temperature rises, the neodymium's power briefly decreases. Avoid using this product in hot environments exceeding its operating temperature limit. Exceeding the critical threshold will cause destruction of magnetic properties.

*Engineering note: Temperature resistance is determined by both grade, as well as the dimension ratios. Low-profile magnets (low Pc) may lose charge permanently at lower temperatures than taller cylinders. The danger warning in the table points to a risk of irreversible loss for this particular item.

Two magnets attract each other from a wider radius than a neodymium and metal combination. Such a system of two magnets creates a more powerful interaction and a wider radius of action. Want to build a strong closure? Utilize two neodymiums instead of a neodymium and a steel. Exercise caution that when bringing together two magnets, the collision energy is massive. The levitation is a bit weaker than the connection force, but still impressive.
*The magnetic induction between like poles drops to ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
* Figures refer to sliding force of two identical magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field poses a real danger to electronics and medical implants. These NdFeB products generate a field that prevents correct functioning of sensitive medical devices. Be aware: the unseen radiation penetrates the body and housings. Special caution must be taken by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, car keys, speakers, and displays. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Table 8: Collisions (kinetic energy) - warning

100 mm	162.27 km/h (45.08 m/s)	0.91 J

Neodymium magnets are very brittle – a collision with steel risks their cracking. Watch the impact speed – a neodymium left loose turns into a projectile. Impact energy can destroy the magnet or injury to skin. Be sure to control the product during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear eye protection when handling with powerful specimens.

Warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

The magnetic field penetrates through water without any losses. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Sliding resistance

*Note: On a vertical wall, the magnet holds just ~20% of its nominal pull.

2. Steel thickness impact

*Thin metal sheet (e.g. computer case) significantly weakens the holding force.

3. Heat tolerance

*For standard magnets, the safety limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.32

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. The solid red line represents the demagnetization curve (material potential), while the dashed blue line is the load line based on the magnet's geometry. The P_c (Permeance Coefficient), also known as the load line slope, is a dimensionless value that describes the relationship between the magnet's shape and its magnetic stability. The intersection of these two lines (the black dot) is the operating point — it determines the actual magnetic flux density generated by the magnet in this specific configuration. A higher P_c value means the magnet is more 'slender' (tall relative to its area), resulting in a higher operating point and better resistance to irreversible demagnetization caused by external fields or temperature. A value of 0.42 is relatively low (typical for flat magnets), meaning the operating point is closer to the 'knee' of the curve — caution is advised when operating at temperatures near the maximum limit to avoid strength loss.

Model MPL 20x3x2 / N38 features a low profile and industrial pulling force, making it an ideal solution for building separators and machines. As a magnetic bar with high power (approx. 2.33 kg), this product is available off-the-shelf from our warehouse in Poland. Additionally, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.

Separating block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 20x3x2 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend extreme caution, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

They constitute a key element in the production of generators and material handling systems. They work great as invisible mounts under tiles, wood, or glass. Customers often choose this model for workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 20x3x2 / N38, we recommend utilizing strong epoxy glues (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. Remember to clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 20x3x2 / N38 model is magnetized axially (dimension 2 mm), which means that the N and S poles are located on its largest, flat surfaces. In practice, this means that this magnet has the greatest attraction force on its main planes (20x3 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 20x3x2 mm, which, at a weight of 0.9 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 20x3x2 mm and a self-weight of 0.9 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Benefits

Besides their durability, neodymium magnets are valued for these benefits:

They do not lose magnetism, even over around 10 years – the reduction in lifting capacity is only ~1% (based on measurements),
Magnets perfectly protect themselves against loss of magnetization caused by ambient magnetic noise,
A magnet with a smooth gold surface has better aesthetics,
Magnets have very high magnetic induction on the surface,
Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
Possibility of custom modeling and optimizing to individual requirements,
Fundamental importance in electronics industry – they find application in mass storage devices, electric drive systems, advanced medical instruments, and industrial machines.
Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Limitations

Drawbacks and weaknesses of neodymium magnets and ways of using them

At strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Due to limitations in creating nuts and complicated shapes in magnets, we recommend using casing - magnetic mechanism.
Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that small elements of these magnets are able to complicate diagnosis medical in case of swallowing.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

Highest magnetic holding force – what contributes to it?

Magnet power is the result of a measurement for optimal configuration, including:

on a block made of structural steel, optimally conducting the magnetic flux
possessing a massiveness of min. 10 mm to avoid saturation
with a plane cleaned and smooth
with direct contact (without coatings)
during detachment in a direction perpendicular to the plane
at standard ambient temperature

Determinants of lifting force in real conditions

Real force impacted by specific conditions, such as (from priority):

Clearance – existence of foreign body (rust, tape, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
Direction of force – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
Material composition – different alloys attracts identically. High carbon content weaken the interaction with the magnet.
Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.

Safety rules for work with NdFeB magnets

Keep away from children

Absolutely store magnets out of reach of children. Choking hazard is significant, and the consequences of magnets clamping inside the body are tragic.

Nickel allergy

A percentage of the population have a sensitization to Ni, which is the standard coating for NdFeB magnets. Prolonged contact may cause dermatitis. We recommend use safety gloves.

Mechanical processing

Machining of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Do not overheat magnets

Standard neodymium magnets (N-type) lose power when the temperature surpasses 80°C. The loss of strength is permanent.

GPS Danger

Navigation devices and smartphones are highly sensitive to magnetism. Direct contact with a strong magnet can decalibrate the sensors in your phone.

Caution required

Use magnets with awareness. Their huge power can surprise even professionals. Plan your moves and do not underestimate their force.

Safe distance

Powerful magnetic fields can erase data on payment cards, hard drives, and storage devices. Stay away of at least 10 cm.

Medical implants

Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.

Shattering risk

NdFeB magnets are ceramic materials, which means they are prone to chipping. Clashing of two magnets will cause them shattering into small pieces.

Bone fractures

Large magnets can smash fingers in a fraction of a second. Never place your hand betwixt two strong magnets.
